HOLDER FOR CAR AND LOCOMOTIVE REPLACING FROGS.

Application filed June 11,

To all whom it may concern Be it known that I, DARWIN E. KEITH, a citizen of the United States of America, residing at Fort forth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Holders for Car and Locomotive Replacing Frogs, of which the following is a specification.

My invention relates to car replacing frogs and means for holding the frogs in place while the re-railing takes place; and the object is to provide simple frog holding devices which will be strong and durable and which will be highly efficient for the purpose and which can be manufactured at relatively small cost. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Figure 1 is a plan view of a portion of a railway track and two re-railing frogs placed along on the side of the rails, as if for re-railing and showing the frog holders applied. Fig. 2 is a side elevation of one of the frog holders and showing in dotted outline the position of a rail and a frog. Fig. 3 is a plan view of a shoe for the frog holder.

Similar characters of reference are used to indicate the same parts throughout the several views.

The invention is shown applied to frogs placed against railway rails. In the drawings rails 1 and 2 of a railway track are shown and frogs 3 and 4 are shown against the rails in position for re-railing. The frog holder consists of a flat bar 5 having an upstanding flange 6 and has a plurality of holes 7, and a shoe which is adjustable cn the bar 5 and is held at any point of adjustment by bolts 9 which project through any pair of holes 7 in bar 5. The shoe has an upstanding member composed of lapped arms 10 and 11 which are bolted together by a bolt 12. The flange or hook 6 and the shoe form two gripping members and the frog and the rail are held together by the two gripping members, or rather the frog is held against the rail by the two gripping members. A bolt 13 may be inserted in the end of the bar 5 to prevent the Specification of Letters latent.

shoe from leaving the bar 5. It is necessary to use two frog holders in a re-railing operation, as shown in the drawings.

The shoe 8 may be made from flat malleable sheet iron by cutting two members 14 and bending them over as shown in Fig. 3 to form sleeve to receive the bar 5 and slide thereon. The parts 10 and 11 are cut and bent to form th cooperating gripping member. The device is shown by actual service to be entirely satisfactory in re-railing operations.

Tie bar 5 should be curved upwardly slightly approximately at the point 15 so that the bar and gripping member 6 will fit the rail or frog snugly. The holes 7 should be staggered relative to each other for purpose of adjusting the shoe 8 thereto and the holes 16 should also be staggered in a similar manner. This arrangement makes it possible to place the shoe 8 and the gripping member 6.

The frog holder herein shown is simple in construction and requires no change in the construction of the frogs for engaging and holding the frogs. The positioning of frogs by spikes driven into the cross-ties is eliminated and the re-railing of cars and locomotives is made easy and much time is saved in the operation. Another advantage is that no special tools are necessary for using the frog holder in a re-railing operation.

l/Vhat I claim, is,

1. A frog holder comprising a bar having an upstanding inclined gripping member integral therewith at one end and an upward bend in said bar near said gripping member, a shoe slidably mounted on said bar and consisting of a body member mounted under said bar and lateral members bent above said bar and bolted together and forming an inclined gripping member for cooperating with the gripping member on said bar, and means for positioning said shoe at different adjustments on said bar.

2. A. frog holder comprising a bar having a series of holes therethrough in one end and an upstanding inwardly inclined gripping member at the other end, a shoe having a sleeve slidably mounted on said bar and provided with holes adapted to register with a pair of holes in said bar and having an upstanding gripping member for cotiperating with said first named gripping member, and bolts for positioning said sleeve at diff rent points of adjustment on said bar.

3. A frog holder comprising a bar having an upstanding gripping member, a shoe having a sleeve member consisting of lateral members bent over in plane parallel to the body of: the shoe and having an upstanding gripping member consisting of lateral members bent upwardly and above the body of the shoe and bolted together, and means for positioning said shoe at different adjustments on said bar.

In testimony whereof I set my hand this 27th clay of May, 1921.
